Moving on from Superfish

What a month it's been for Lenovo, the world's top supplier of PCs and generally a well liked company. The OEM put both of those traits at risk by pre-loading adware onto its consumer laptops and desktops, adware that was later discovered to be a serious security threat. We might never know for sure how savvy Lenovo was to the software's nefarious methods of serving up ads, but in the wake of it all, there have been apologies, explanations, a software tool to remove Superfish, a class action lawsuit, and now a promise -- Lenovo wants to be the leader of clean PCs.

Old school vets remember when CCleaner was called Crap Cleaner. Piriform launched the freemium utility almost a decade ago, and we still like to use it after all these years to clean up unwanted files and cache that tends to accumulate. So do many others, which would explain why it's been download more than a billion times, according to Piriform. Remarkable, CCleaner has been installed on one quarter of the world's PCs and now spans 200 countries and more than 45 languages.
